Questions

Is there a KiCad symbol and footprint for the SMF43A?

Yes. The symbol is Diode:SMF43A and the footprint Diode_SMD:D_SMF, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMF43A?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where can I order the SMF43A?

JLCPCB lists it as part C266698, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SMF43A?

Parts like it in the library: the SMF43A by FOSAN, the SMF43A by JSMSEMI, the SMF43A by Liown and the SMF43A by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
